(6)high/low voltage active power filter and passive power filter series. With a number of competitiveness patent technology, parts of energy-saving products have passed the test of Ningbo Energy Conservation Center and listed as "Ningbo Key Promotion Energy-saving Products", incorporated into the "Ningbo Energy-saving Technolgoy(Product) Catalog", at the same time, our company has passed ISO9001-2000 international quality system certification and assured by China Quality Guarantee Center. Application GWG-J series Coreless Medium Frequency Induction Melting Furnace is for melting steel, iron, stainless steel, copper, aluminum and other metals or its alloy. It can also be used together with self-heated furnaces and electric arc furnace for heating or keeping warm/holding the molten iron and molten steel. It is particularly suitable for medium size or big enterprises. Structure Feature 1. Solid steel structure and durable; 2. Good magnetic isolation, safe and reliable; 3. Solid frequency conversion power supply, easy operation; Adjustable power rate, easy operation and maintenance; 4. Easy to start up with load or free of load. Electrical Feature: 1. Digital CMOS chip (U. S. ASIC-2-12), with the highest degree of integration at home, is used in control circuit, the overall machine controlled through one single panel; 2. Frequency-sweep zero voltage start, high success rate, no shock; 3. Automatic resistance adjustment, permanent power output, 10-20% energy saved in comparison with domestic traditional machine of the type; 4. Auto phase sequence adaptation, free of synchronization; 5. Good performance in reload staring, auto recovery; 6. Highly integrated in controlling circuit, free of use of high-rate starter and relay loop, fairly low failure rate; 7. Wholly digital design, strong in anti-interference, no temperature shift when in continuous working; 8. Multi-protection functions (for over current, over voltage, insufficient water pressure, power failure, or phase absence), and mishandling will not cause damage to machine.
